If I'm getting a lift to watch rugby, then it's a Whisky Mac - 50/50 whisky (but not a decent one!) and green ginger wine. If I'm driving to the game, once I'm back home afterwards, two or three will often help a defeat become just a little easier to bear!
Strange that upon asking for a Whisky Mac in pubs and bars, the serving staff very often don't know what you're talking about, even here in Scotland ...
